Ever use this stuff? It's like putty but it's silicon so it dries sort of hard-ish and can be used to repair and hack all kinds of things. If you look in the gallery on their website you'll see lots of incredible projects. http://sugru.com/
Here are a few of mine. I don't work for them, I just love the stuff
Turn and "L" fridge magnet into an "I" (I cut part off with a carpet knife then filled it in with red sugru.
Fix a ripped shower curtain ring.
Heat and slip-proof metal camping dishes, works to personalize sets too
Fix an uncomfortable knife grip.
Mend a broken clasp on your kid's arts and crafts lap table/storage unit.
Make a dollar store paper towel holder into a handy canning jar ring stash tower (these things were EVERYWHERE before I did this!).
